    Hydrofluoric acid - used for transparent etching of silicate glass

    Hydrofluoric acid is a colorless liquid. The dissolution of hydrogen fluoride in water is accompanied by a rather significant release of heat (59.1 kJ / mol). It is characterized by the formation of an azeotropic mixture containing 38.3 HF and boiling at 112 ° C (according to other data, 37.5 and bp 109 ° C). Such an azeotropic mixture is ultimately obtained by distilling both strong and dilute acids.

    A large consumer of hydrofluoric acid is the aluminum industry.

    A solution of hydrogen fluoride is used for transparent etching of silicate glass (for example, the application of inscriptions - for this, the glass is covered with paraffin, cutting holes for etching). Matt etching is obtained in hydrogen fluoride vapor. For etching silicon in the semiconductor industry.

    As part of etching, etching-polishing mixtures, solutions for electrochemical processing of stainless steel and special alloys.

    Getting fluorides , silicofluorides and borfluorides, organofluorine compounds, and the corresponding acids (hydrofluorosilicic acid and hydrofluoric acid), synthetic lubricating oils and plastics.
